A ball is dropped from a height of 16 feet. The ball bounces. After each bounce, the height attained by the ball is 65% of the previous height. Write an nth term formula to model the situation. What is the maximum height attained by the ball after four bounces?1.86 feet

0.24 feet

4.39 feet

2.86 feet

Answers

Answer 1

Answer: 2.86

After the first bounce, it is 10.4 feet
after the second, it is 6.76
after the third, it is 4.39
after the fourth, it is 2.86

What is the median of Variable B? Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variablea. The vertical axis is labeled Variable
b. Points are plotted at (two, two), (two, eight), (four, three), (five, one), (six, three), (seven, five), (eight, six), (nine, two). I'm really confused can you please help me

Answers

Variable A - horizontal axis ⇒ xVariable B - vertical axis ⇒ y
points (x, y) A B1) 2 , 22) 2 , 83) 4 , 34) 5 , 15) 6 , 36) 7 , 5 7) 8 , 68) 9 , 2

Median of a set of data is the middlemost number in the set. We need to arrange the numbers in order from least to greatest and find the middlemost number of the set.

B = 2, 8, 3, 1, 3, 5, 6, 2

There are 8 numbers that we need to arrange in order.

1, 2, 2, 3, 3, 5, 6, 8

Since the data set is even. We need to look for the middle two numbers and find its average.

3 + 3 = 6
6 ÷ 2 = 3 IS THE MEDIAN of Variable B.

Which expression represents the total perimeter of her sandwich, and if x = 1.2, what is the approximate length of the crust?8x2 + 34; 43.6 centimeters
8x2 + 34; 45.52 centimeters
4x2 + 17; 21.8 centimeters
4x2 + 17; 22.76 centimeters

Answers

Substituting the value of X in each of the equations.The best answer would be the equation satisfying both of the sides.
Therefore,
Substituting the values in the second equation gives the best answer.
8(1.2)^2 + 34 = 45.52 centimeters

The correct answer is the second option.

B) 8x2 + 34; 45.52 centimeters

Sample annual salaries (in thousands of dollars) for public elementary school teachers are listed. Find the sample standard deviation. Round to two decimal places if necessary 23.9
15.3
40.2
30.3
21.0
22.8
ID: ES6L 2.4.1-9+

Answers

Answer:

The standard deviation is 9.34

Step-by-step explanation:

First we need to find mean of the sample:

$m=(23.9+15.3+40.2+30.3+12+22.8)/6=24.08$

Standard deviation will be like below:

$d=√((x-m^2)/6)=9.34$

Will mark brainliest for this: A rectangle is mesured 3 cm by 6 cm. Three of theses rectangles are put together to make a larger rectangle. Work out the perimeter of the larger rectangle it is: 3 cm x 2 and 6 cm x 2 plus the height of the the two rectangles times 2 Hope this makes sense if you have any questions feel free to ask me

Answers

Answer:

Step-by-step explanation:

total length = 6 + 6 + 6 = 18 cm

total breadth = 3 + 3 + 3 = 9 cm

perimeter = 2 ( l + b )

= 2 ( 18 + 9 )

= 2 × 27
